Massachusetts's breach notice rule

Massachusetts covers breaches in General Laws chapter 93H, section 3, with definitions in section 1.

Notice goes, as soon as practicable and without unreasonable delay, to the attorney general, to the director of consumer affairs and business regulation, and to the affected resident.

The two state offices also receive a sample copy of the consumer notice. There is no resident count that switches the state notice on; it travels with the resident notice.

Two ways the duty is triggered

The duty arises when a business knows or has reason to know of a breach of security, or knows or has reason to know that a resident's personal information was acquired or used by an unauthorized person or used for an unauthorized purpose.

A breach of security is itself defined as unauthorized acquisition or use that creates a substantial risk of identity theft or fraud against a resident. The second trigger stands on its own, so the substantial-risk test does not answer every case.

Our Massachusetts breach notification page sets out the data elements and the rule in full, and says which text we checked. This is general information, not legal advice.

What a ShareAndGo room gives a Massachusetts team

After an incident, a precise view of file activity is valuable.

For documents you share through ShareAndGo, the activity log records every view and download, and watermarked view-only pages carry the reader's email address and the date.

The watermark is a per-room setting, on by default. The log is chained, exportable as CSV, and also covers invitations and changes. Because groups see only their own folders, the set of possible readers for any document is defined in advance.

The courts and regulators behind Massachusetts paperwork

Federal cases from Massachusetts are heard in the U.S. District Court for the District of Massachusetts, whose Boston courthouse is the John J. Moakley Courthouse. CPAs practicing in Massachusetts are licensed by the Massachusetts Board of Public Accountancy.
